Freeze-drying is a widespread technology particularly suitable for heat-sensitive materials such as pharmaceuticals that could be damaged by the high temperature required by traditional drying treatments. A freeze-dryer is composed of two chambers: drying chamber and condenser, connected ... En savoir plus

Ultrasonic nondestructive testing (NDT) is extensively used in fields like medicine, oil and gas, and aerospace to inspect materials without causing damage. However, developing experimental setups and prototypes can be costly and time-consuming. This study employs advanced computational ... En savoir plus

MEMS microphones have been widely adopted in a variety of consumer electronic systems. To ensure clear speech transmission and avoid degradation of important signals, careful tuning of microphone port geometry is essential to mitigate wind-induced airborne noise. This additional noise ... En savoir plus

Electroformed Ni-based 3D electrodes (NiE3) offer a novel approach to enhancing alkaline electrolysis performance by increasing surface area and active sites, leading to intensified electrolysis reactions and improved efficiency. However, inefficient bubble release from the produced ... En savoir plus

This paper focuses on the acoustic modeling and simulation of a simplified minute repeater watch using the Boundary Element Method (BEM). The overarching objective is to optimize the hammer's impact location on the watch's gong (timbre) to enhance both the radiated acoustic intensity and ... En savoir plus

INTRODUCTION: The paper illustrates the use of COMSOL for obtaining the solution Ψ(x,y,t) as a solution to the time dependent nonlinear Schrödinger equation (NLSE). COMSOL previously was used to solve the time dependent NLSE in Ref.[1] as applied to quantum mechanics, however this is the ... En savoir plus

Recognized for its potential as a sustainable food source, seaweed farming has become pivotal in tackling future food security concerns, necessitating innovative solutions to achieve optimal, high-yield, and commercially viable production [1]. This work addresses gaps in aquaculture ... En savoir plus

Dams, levees, and dikes play a critical role in flood prevention. There can be simple earthen embankments or engineered designs with low permeable cores and/or drainage facilities. Unlike cement dams there is flow of water in earthen embankments. The latter are unsaturated in the upper ... En savoir plus
